BODEM 2/04/2020: Climate adaptation - The magic word 'Nature-Based Solutions'
The many challenges facing our soils, from historical pollution to climate change, require new solutions. Nature-Based Solutions are such a new track and a number of these techniques are currently being investigated in pilot projects in Flanders and the Netherlands - with Europe just around the corner - for the effectiveness and application possibilities of 'working with nature'.. ... RESANAT stands for 'remediation of residual pollution using nature-based techniques' and is a Flemish-Dutch collaboration to refine a number of remediation techniques for PAHs and oil. In RESANAT seven small and large companies from the Netherlands and Flanders (iFLUX, Tauw Group, bio2clean, Jan De Nul NV, Witteveen+Bos Belgium, Dura Vermeer Infra Milieu, TTE Consultants) collaborate with knowledge institution Deltares and OVAM to stimulate the redevelopment of polluted sites in the Netherlands and Flanders. ... The LIFE project NARMENA ('Nature-based Remediation of Metal pollutants in Nature Areas to increase water storage capacity') deals with the approach to the remediation of water soils. For this purpose OVAM wants to develop and implement nature-based remediation methods that are both cost-effective and non-invasive in watercourses, riverbank zones and valley soils in Natura 2000, nature reserves and flood plains. OVAM is implementing this project together with the Agency for Nature and Forests and Natuurpunt, which owns and manages the nature areas. The Vlaamse Milieumaatschappij, as watercourse manager, is also a partner in this project together with the experts in the field of soil research and remediation ABO NV, bio2clean (phytoremediation) and ARCHE Consulting bvba (ecomodelling). ... read moreRead more
TRENDS 19/03/2020: Trees eliminate oil pollution!
Trees eliminate oil pollution. Plants and bacteria that eliminate pollution. That is the basic idea behind bio2clean. A European pilot project should help convince the market. Poplars, willows, sea buckthorn, reed, cattail and grasses, supplemented with micro-organisms. The technology applied by the young bio2clean to tackle pollution at the Carcoke site in Zeebrugge is quite green. The remediation is part of RESANAT, a European demo project in which six companies from Belgium and the Netherlands, the Public Waste Agency of Flanders (OVAM) and the knowledge company Deltares are testing environmentally friendly remediation methods. For bio2clean, the project must provide further proof of the quality of its technology. It was developed by Professor Jaco Vangronsveld, director of the Centre for Environmental Studies (CMK) at Hasselt University. He came up with the idea of crossbreeding bacteria that promote plant growth with bacteria that can break down pollutants. The first major field test with phytoremediation, as the technique is called, took place in 1999 at Ford Genk, which wanted to eliminate toluene and benzene pollution. After four years, the plants appeared to have eliminated a large part of the pollution. At the former car builder, Dirk Dubin was one of the great promoters of the new approach. The Hasselt industrial engineer in chemistry worked at the environmental department, responsible for water treatment and soil remediation, and was the driving force behind the ISO 14001 environmental care system. "I immediately saw the possibilities. Phytoremediation has a small ecological footprint and is a lot cheaper. You don't have to dig up the soil and have it cleaned, or have machines pump up and purify water for years". "Although we are often much cheaper, many people do not take it for granted to put forward a less well-known technique such as ours. Less known Dubin founded bio2clean in 2015 as a spin-off from CMK, together with Mario Clemmens, a geologist and former soil remediation expert who has been running an environmental consultancy since 2005. Bio2clean focuses on the remediation of organic contaminants, such as oil, the solvent tetrachloroethylene (TCE) and the oil derivatives benzene, toluene, ethyl benzene and xylene (BTEX). "Traditional soil remediation is expensive and has a major impact on the environment", Dubin knows. "With the right mix of plants and micro-organisms you can eliminate the pollution and prevent it from ending up in groundwater.Read more
EUROPEAN DEMO PROJECT RESANAT LAUNCHED
Remediating residual pollution with nature-based techniques, that's what RESANAT stands for. At three locations in Flanders and the Netherlands, nine partners will give their best in this European Interreg project, with the aim of increasing the practical applicability of nature-based techniques and developing codes of good practice.Read more
